ToaZZ whom 'it 'may concern:

Be it known that I, WILLIAM M. SIMMONS, a citizen'of the United States,residing at. Burlington, in the county of Des Moines and State of Iowa,have invented certain new and useful improvements in Means for OperatingDoors of Vehicles; and I do hereby -declare the :following to be a full,clear, and enact description ot the invention, suoli as will enableothers skilled in the art to which. it appertains to make and use thesame.

My invention relates to improvements in means foroperating doors ofvehicles and A plunger 5 is also Inountcdin thetabulaeinorevpai'ticularfij; to opening and closing means for the doorsof automobiles,oiie

object ot' the invention being to so construct vehicle door operatingmechanism that the door cannot be opened or closed without operating`the emergency' brake of the machine.

lA Jfurther objectis to construct and arrange vehicle door operatingmechanism, in

such manner, that the application of the emergency brake will i'enderthe door operating mechanism operable tor opening the `door when thelatter has been unlatched.

A further object vis to so construct the devices that the.release of theemergency 'brakel will operate to render the door oper# ating mechanisminoperable to open the door.

A further object is to provide door operating mechanism for veliioleswhich will serve to Vprevent the opening of the door when the vehicle isin motion, and to insure the closing` of the door when the brake isreleased on the starting ofthe vehicle.

'Witt these and other objects in view, the invent vn consists in certainnovel features of 4construction and combinations o t parts ashereinafter set foi-th' and pointed out in 1n the accompanying drawings,Figure 1 is a view showing the application of my improvements; Fig. 2 isa view showing the positionsof the parts when lthe doors are open, andFig` Sis a View showing the positions' o1" the parts when the doors areopen.

1 represents portions of an automobile body provided with a hingeddoor?, in one orboth sides. The door 2'is provided with a latch 3 toengagein a tubular keeper 4 mounted in the body 1, said latch being ofanj, woll known or. approved construction.

{eeper 4 and is provided with stem 6, with which latter, one end of' apitman 7 is connected, the other end of saidpitinan being connected withthe crank Soli an operating lever 9. A spring wenen-cling the steintends to retain the plunger 5 at the rear end of its throw (with thelatch 3 engaging the keeper) and the lever 9 .in its normal position. Bvmoving the lever 9 from its normal position, the plunger-5 will be movedrearwardly and, engaging the latch 3, will move the -latter out oflocked: relation to the keepenthusv unlocking the door.

vVihile door locking devices will be einployed in conjunction with theopening and closing mechanism hereinafter described, the specificconstruction of locking or latch devices hereinbefore described does notcon? stitute a part of the invention herein claimed, but is made thesubject of a separate application tiled even dat-e herewith.

When the automobile is provided with diametrically opposite doors, each.of said doors has secured `thereto adjacentfto its hinged edge,abracket 11 to which one end of a rod or pitinan 1Q ispivotally.connected. The other end of each rod or pitman 12 is pivotallyattached to a coupling block 13. A horizontal shaft 14 is suitablymounted'- on the vehiclevand providedat its ends withupwardly-projecting arms 15, the upper portion Aof cachot the latterbeing pivotally connected with one of the coupling blocks 13. 1t isapparent that if the shaft 14 be turned in one vdirection motion will beimparted, througharins 15, coupling blocks 13, rods 12l and brackets 11,to open .thedoors and that motion of said vshaft in. the reversedirection will cause the doorstobe closed, The shaft14-is providedbetween itsends with an arm 1G which. enters a slot. 17 ina block'1'8-.This block is also provided withAv slots 19 in which a pin 20, securedto the arm 16 is movable, and tothis pin, one end of a spring 211sconnected, the vother end of hand. lever26otthe emergency brake is sel,-

c'ure'df. When, the .doors are closed `and the brake ,leven is jinrelease. positkon, as shown-Jin Vto open'said doors.

will project forwardly and downwardly from said shaft. The brake leverwill Abe hold in this position by the detent and seg ment devicescommonly employed with such levers, and mnscqnently, the shaft 1st willbe prevented from tmning, and the doors will therefore be retainedlocked in their closed positions.

In bringing the car to a stop, the operator will apply his emergencybrake and in doing so, he will move the block 1S rearwardly on the pin20, and, as the doors are still latched, the tension of the spring Q1.

will remain on the arm 16. The ear having come to a. stop, the operatorwill manipulate the lever 9 to release the latches of the doors from'their keepers, -whereupon the spring 21 will be free to turn the-shaft14 and impart motion to the doors, as above described, Motion of thebrake lever in a direction to release the will operate the shaft 1dinthe re o direclion and close the doors, permitting their latchesautomatically to engage t-heir keepers.

From the construction and arrangreinent of parts herein described, itwill be seen the doors cannot be opened while the brake is in releasedposition', and that said doo 's can be opened only after the brake hasbeen applied. c

Various changes'might be made in the details of construction of myinvention With- -out departing from the spirit thereof or limiting; itsscope and hence I do not wish to restrict myself to the precise 'detailsherein set forth.

Having,` fully described myinvention what I claim as new' and desire tosecure by Letters-Patent, v

It. :ln door operating mechanism for automobiles, the combination with adoor and a brake lever, of devices connectingthe door with the brake.lever and tending to lock 'the door when the brake lever is in releasedposition and tending to open the door when the bral-:e lever is moved tosetthe brake.

2. Indoor operating mechanism for automobiles, the. combination with adoor and latch devices therefor, ofva rock-shaft, connections betweensaid rolt-shaft andthe door, an arm o n said shaft, an oierat-ing lever,a rod connected with said lever and having sliding connection with saidarm on the rock shaft for turning` the latter in one direction, meansfor locking said lever to lock the rock shaft, and means for rock-A ying said shaft in the other direction when the operating lever is movedrearwardly.

8. In door operating mechanism for automobiles, the combination with adoor and a brake lever, ofv operating devices connecting I tion.

the brake lever with the door for closing the latter, latch devices forthe door, means for operating said latch devices to release the door,and a springY connected with said operating 'devices for opening thedoor when the brake lever has been moved to set the brakes.

4t. In door operating mechanism for automobiles, the combination with adoor and a brake lever, of a rock-shaft, an arm projecting from saidshaft, lost-motion connections between said arm and the brake lever forturning said shaft in one direction, means for locking said brake leverto lock the shaftin one position, another arm on said shaft, connectionsbetween said last-mentioned arm and the door, and a spring for turningsaid sha ft in the reverse direction when the lever is in" set position.

5. In door operating mechanism for automobiles, the combination with adoor and a bra ke lever, of a. rock-shaft, an arm on said shaft, pivotalconnections between said arm and the door, a spring connectedwith saidarm for turning said shaft in a direction to open 4the door, another armon said shaft,

lost-motion connections between said lastmentioned arm antL the brakelever, and means forlocking the brake lever to lociA the shaft when thedoor is closed and the brake lever is in release position.

6. In door operating,` mechanism for antomobile doors, the combinationwith a door and a brake lever, of a shaft, an arm on said shaft,connections between said arm and the door for imparting motion tothe-latter, another arm on said shaft, a block having two slots intoo-ne of which said last-mcn tioncd arm enters, a pin on saidlastanentioned arm and movable in the other slot of said bloeit, a rodattached to said block, conneet-ions between said rod and the brakelever, and a springr fixed at one cnd and connected at its other endwith the pin on said last-mentioned arm.1

7. In door operating mechanism, the combination with a door, a lever,and means fon locking` the lever, of connections between said lever anddoor for olosingrand locking` the door when said lcveris'nnived in onedirection, and a spring cooperating to said connect-ions and tending toopen tliedoor when said lever is moved in. the other direcln testimonywhereof, I have signed this specification in the presence of twosubscribmg witnesses. y
